上海市火电行业NOx排污费征收标准及情景分析
China Environmental Science(2011)
Abstract
基于火电行业典型样本的脱硝成本,以调整排污征收标准使得企业得到相对收入,即未脱硝捧污费大于脱硝后总支出为判别标准,得出NOx捧污征收标准最低值应为1.2元/0.95kg,最终需达到4.0元/0.95kg以上,当征收标准为1.2~10.0元/0.95kg时脱硝总支出占单位电量收入为0.50%/~5.0%.根据情景分析,"十二五"征收标准为1.2元/0.95kg时5a总捧污费达3.4~4.4亿元,如作为推动企业脱硝建设补贴资金来源,则可补贴额度为23~30元/kW,占实际建设支出的23.1%/~30.6%,单位电量总支出占单位电量收入比例为1.5%~1.6%."十三五'NOx排污征收标准调整为2.4元/0.95kg时5a总捧污费为2.9~4.4亿元,可作为NOx超量削减奖励资金,发挥经济杠杆作用,挖掘脱硝设施减排潜力.
